1. Simple/compound pendulum
The purpose of this experiment is understanding the relations between simple and compound pendulums. First, we will analyze a simple pendulum that have point mass and string of constant length. And, we will also analyze a compound pendulum having a specific shape. To interpret compound pendulum system, we need to know the concept of the center of percussion and the effect of a pendulum's rotational motion. In this experiment, we will measure period of a simple pendulum and review the results as compared to the experimental values, based on the theory. And we will calculate length of the equivalent simple pendulum in a compound pendulum.
2. Free Vibration
If mechanical system is modeled by mass, springs and dampers, have small initial velocity, it start to vibrate spontaneously. We call it 'free vibration'. In this system, the equivalent stiffness depend on the ways of the spring connections.
